“Yet the writers of the Bible claimed it as uniquely their own of their own God.”
Nope. Did not happen. That is not claimed at all. You cannot find a single verse in the Old Testament to that effect. The Biblical writers claimed that the God they revealed was uniquely their own. You need to find another object of your anti-Christain venom. You people amaze me. That statement you just made. You just took ownership of it, but it is certainly not your own. You got it from other sources. That was once common knowledge.
And in the age of exploration during the 1700s and 1800s, explorers discovered isolated cultures that had a flood myth. The American Indians told Buffalo Bill of giants that once roamed the land.
Genesis 6 is hardly explained since it was such common knowledge, across cultures, at that time, except all the other cultures thought it was a great thing, when “gods” walked among men.
“Nope. Did not happen. That is not claimed at all.”
Yes they did... And you yourself are right now. The Bible is the only source that is to be righteous period, all others are false. This is absolutely a claim of uniqueness.
“You need to find another object of your anti-Christain venom.”
I am not anti-Christian at all... I am just an open minded historian with no ignorant biased mental firewalls that prevent and block out discovery of the whole picture in history.
